Tire patching thirty, yet air inflation costs fifty! Just after paying his maintenance fee, Lin Shuo was publicly mocked by his boss: you can afford a car worth hundreds of thousands, yet you can't afford fifty yuan for air inflation? He scanned the code to keep a receipt, only to discover old parts passed off as new, and faulty cars being stamped and cleared for release! Just as the accounts started yielding clues, a cold chain truck nearly overturned on the elevated highway. The driver was injured, Lin Shuo was suspended, and the black-hearted boss even turned the tables to bite back that he colluded with a new shop and gambled with the lives of the entire fleet! On one side is the safety of seventy-two vehicles, and on the other is the black ledger of a ten-year-old shop. The boss went live to cry and play the victim, while Lin Shuo stepped up with twenty-seven work orders: you dare collect fifty yuan, but do you dare acknowledge these twenty-seven accounts?
